Specification of Letters Patent.

Patented May 27, 1919;

Application filed May 1 5, 1918. Serial No. 234,713.

To all whom it may concern Be it known that I, SALVATORE BARBER, a subject of the King of Italy, residing at Long Island City, county of Queens, and State of New York, have invented certain new and useful Improvements in Shoes, of which the following is a specification, reference being had therein to the accompanying drawings, forming part thereof.

My invention relates to shoes of that type or kind in which theouter sole and the outer part of the heel which are subjected to the greatest wear and which form the tread of the shoe are detachable by the wearer, so as to be renewed or replaced by the wearer with a new or fresh set of soles and heels, and the object of my present invention is to so improve this type of shoe, which heretofore has not come into general use, as to make it practical, in order that the inherent and obvious advantages thereof may be fully utilized by the public. In this connection one of the objects of my invention is to provide a shoe of the above mentioned kind which in substantially all respects has the same general appearance as the ordinary shoe heretofore made with permanently attached outer sole and heel. A further ob ject is to so construct the shoe of my invention that it will feel substantially the same upon the foot of the wearer and give the same comfort as shoes heretofore made with permanently attached outer sole and heel. Also important but more general objects of my invention are durability, dependability, inexpensiveness of manufacture of the shoe as a whole and also of the parts to be furnished for renewal, simplicity of construction. Also all of the general advantages heretofore possessed by shoes notembodying my invention, together with other ob jects and advantages which will hereinafter appear.

Myinvent-ion includes features of construction and combinations of parts, as will appear from the following description.

I shall now describe the shoe embodying my invention illustrated in the accompanying drawings and shall thereafter point out my invention in claims.

Figure 1 is a longitudinal section, with the upper part in elevation, of a shoe cmbodying my invention;

Fig. 2 is a transverse section on a vertical plane indicated by the line 2-2 of Fig. 1'

as viewed from the right.

Fig. 3 is an enlarged transverse section corresponding to what appears at the right in Fig. 2.

Fig. 4 is a bottom view or inverted plan view of the shoe shown in Fig. 1, but with the outer detachable sole and heel parts removed.

Fig. 5 is a plan View or view of the upper side of the outer detachable sole, which appears in longitudinal section in Fig. 1.

Fig. 6 is a similar view of the outer detachable heel part.

Fig. 7 is an inverted plan view or bottom view similar to'what appears at the right in Fig. al but with the upper or permanent heel part also removed for showing the studcarrying metal plate above and held in place by said upper permanent heel part, these parts appearing in longitudinal section in Fig. 1.

The shoe embodying my invention illustrated in the accompanying'drawings comprises a usual upper 1, an insole 2, which may be of usual construction excepting as slightly modified by the embodiment therein of features of my invention, and ausual welt 3, between the upper side of which and the lower side of the outer margin of the insole 2, the lower edge of the upper 1 is secured, these three parts all being secured together in any suitable way, such, for. ex-

ample, as by means of nails 4, shown in Fig;

4 of the drawings. The inturned lower edge of the upper 1 is also preferably lasted or nailed to the margin of the insole 2 independently of the securing in place ofithe welt 3, some of these nails 5 appearing at the right in Fig.7 beyond the tapered end 6 of the welt 3. Y

A plurality, shown as four in number, of strong metal straps 7, 8, 9 and 10 are firmly secured at their ends to the opposite edges of the insole 2, which forms a permanent sole member, and these straps extend transv'ersely across below the insole 2 in slightly spaced relation thereto so as to form loops or keepers below and carried bythe insole 2. Each end of each of the keeper-forming straps 7, 8, 9 and 10 is shown as turned upward through a slit formed in the margin of the insole. 2 and is thence turned outward and downward over the edge of the insole 2 and thence is turned inward in overlapped relation upon itself between the lower side of the insole 2 and the upper surface of the inturned lower marginal edge of the upper 1, as clearly shown in Figs. 2 and 3, thereby producing a very firm and strong connection of the keeper straps 7, 8, 9 and 10 with the insole 2. A thin spring metal plate 11, which may be-of thin sheet steel, is located above or within the keepers formedby the straps 7,8, 9 and 10 and in contact with the lower side of the insole 2, this spring metal plate 11 being of the same general contour as the insole 2, but being of sufficiently smaller size or area to be received within the loops or keepers 7, 8, 9, 10 and 11, and is shown of substantially the same size and as fitting snugly within the central space left clear on the bottom of the insole 2 within the marginal welt 3. At the toe of the shoe the welt 3 is shown as provided with an outer notch 12. The transversely arranged keeper straps 7, 8, 9 and 10 provide for the free bending ofthe insole 2 andother parts of the shoe in use, and the thin spring plate 11 provides resiliency but is not thick enough to interfere with the bending ofthe shoein use.

A permanent heel part is provided and comprises a heel lift 13, which may be built up of one or more thicknesses as desired, and which is shown as having a thinned or tapered forward edge 14 which is adapted to overlie 0r overlap upon the thinned or tapered rear end 6 of the welt 3. This permanent heelpart 13is lasted in place around its margin by means of nails 15, appearing in Fig. 41. This upper permanent heel part 13 firmly and permanently holds in place an upper metal plate 16 of somewhat smaller marginal extent or area than the heelpart 13, so as to come within the curved row of nails 15, this inner or upper inner heel plate 16 appearing in the-drawings in Figs; 1 and 7. The permanent metallic heel plate 16 is provided adjacent to'the forward and rear edges thereof with front and rear outwardly projecting studs 17. and 18 which project outwardly through andsubstanti ally beyond the permanent heel'part 13, which at its forward edge is shown as provided on its lower side with a recess 19 surrounding the forward stud 17, as shown in Figs. 1 andd. Substantially centrally located alined apertures 20 and 21 are provided respectively in the inner metallic heel, plate 16'and in the permanent heel part 13 and are shown in Figs. 1, 4L and 7. Also four shallow recesses 21 are provided in thelower side of the permanent heel part 13 surrounding the central aperture 21 and as shown in Fig. 4c. The purpose of the holes 20 and 21 and. recesses 21 will presently appear.

The parts of the shoe thus far described constitute the permanent or more lasting part of the shoe to the bottom of which the tread parts, comprising detachable sole and. heel parts, are to be attached, these lower or outer sole and outer heelfparts being subjected to the most destructive wear.

A detachable wear-receiving outer sole member 22, which may be of leather or other suitable material, extends from the toe of the shoe, substantially flush with the forward end or edge of the welt 3, back to the permanent heel part 13 and is shown as having at its rear end marginal tapered parts 23 which are adapted to overlap upon the corresponding tapered part 14 of the permanent heel part 13, this tapering or thinning being upon the upper side only and being shown in Fig. 5. Also at its rear end the outer detachable sole 22 is shown as provided with a rearwardly projecting lug or tongue 24 formed in the same piece or integral therewith and fitting into the recess '19 in the outer and forward edge of the permanent heel part 13, this tongue21 being provided with an aperture 25 through which the forward stud or pin 17 of the'inner metallic heel plate 16 is adapted to project as shown in Fig. 1.

On its upper side the detachable outer sole 22 is provided longitudinally along its middle with a series of rearwardly projecting resilient sheet metal tongues 26, 27, 28 and 29 which at their forward ends are firmly secured directly to the detachable sole 22 by means of rivets 30, as shown in Figs. 1 and 5. It is to be noted that in use thes'ole 22 may freely bend between the tongues 26, 27, 28 and 29, and in this connection it is to be noted that the rivets 30 forthe two middle and larger tongues 27 and 28 are arranged along transverse lines for thereby providing for the entire freedom of the sole to bend at all. points between the forwardv tongue, 26 and the rear tongue 29. The sheet metal, attaching tongues, which maybe of steel, are shown as suitably tapered andas rounded at their free ends, and, are shown as slightly overlapping upon each other. The attaching tongues 26, 27, 28. and 29are respectively coiiperative with the transverse loops or keepers 7, 8, 9 and 10 above which and between which and the spring metal plate 11, these rearwardly'projecting tongues are adapted to be slidably inserted so as to project, through and rearwardly beyond the keepers to the extent of about or substantially one-half of. the length of these attaching tongues, the free projecting ends of these tongues at their upper sides resiliently pressing against the metal plate 11, so that space inward therefrom between the spring metal plate 11 and the upper surface of the outer detachable sole 22, these attaching tongues will exert a resilient wedging effect by reason of which the outer edge or margin of the outer detachable sole 22 will be drawn firmly into contact all around with the lower surface of the welt 3, so that no crack or opening will be left at any place, and this action is further facilitated by reason of the fact that the attaching tongues are of graduated width according to the width. of the shoe sole at the point where they are located, for example it being noted that the tongues 26 and 29 at the toe and waist of the shoe respectively are correspondingly narrow, while the middle tongues 27 and 28 are tapered to provide a wide base corresponding to the wider tread portion of the shoe, as is shown in Fig. 5. In order tightly and securely to hold in place the projecting forward end of the outer detachable sole 22, the forward end of the foremost sheet metal tongue 26 is provided with an upwardly and rearwardly turned hook 31 which hooks over the forward edge of the welt 3 at the extreme front or toe of the shoe and which engages in the notch 12 at this point, thereby providing both a smooth finish and a firm engagement of the attaching hook 31 with the welt 3, as will be clear from Figs. 1, 4 and 5.

The outer detachable sole 22 is adapted to be slipped into place in engaging position by a sliding movement of such sole from the toe toward the heel of the shoe, as will be readily understood. For greater convenience in effecting this engagement, the attaching hooks 26, 27 28 and 29 are made of varying length or of varying extent of projection in relation to the spacing or location of the transversely arranged keepers 7, 8, 9

and 10. For example, it has been found convenient to have the free end of the second or largest attaching tongue 27 engage first at the back of the keeper 8, and next after this the next rearwardly located tongue 28 to engage at its free end behind or above the next rearwardly located keeper 9, and then following this the free end of the rearmost tongue 29, at the waist or shank of the shoe, to become engaged above or behind the rearmost keeper 10, and after this to have the forwardly located tongue 26 at the toe of the shoe to come into position for engagement at its free end above or behind the forwardly located keeper 7, following this the hook 31 may be pressed into engagement over the forward edge of the welt 3 at the toe of the shoe, and finally by a firm and gentle pressure upon the toe and heel of the shoe, in which it is of advantage slightly to bend the shoe, the rearwardly projecting integrally formed lug 24 on the detachable sole 22 will readily snap into place over the free projecting end of the forwardly located stud 17 thereby locking the detachable sole 22 in place against forward disengaging movement. The rear end of the detachable sole 22 is held securely and firmly in place and in contact at its marginal edges with the welt 3, and also the lug 24 is held in place upon the stud 17 against disengagement therefrom, by means of a detachable outer heel part, the construction of which will now be described.

A detachable outer wear-receiving heel part 32 is provided and may be of leather or other suitable material and may conveniently be built up of a plurality of layers or lifts, all firmly secured together, for example by means of nailing from both sides and as is indicated at the upper side thereof in Fig. 6 by the nails 33 around the margin. Upon its upper side the outer detachable heel part 32 carries a metallic supporting plate 34 which is firmly secured in place by means of screws 35, shown as four in number. In the construction illustrated in the drawings these screws 35 have a usual form of round projecting heads for thereby obtaining a maximum of strength for holding in place the supporting plate 34, and these projecting screw heads are adapted to be received into the small recesses 21 provided therefor on the lower side of the permanent I I heel part 13. The supporting plate 34 is countersunk into the material of the outer heel part 32, and at its forward end is shown as flush with the forward end of said outer heel part, as is clearly shown in Figs. 1 and 6 of the drawings. 7

When the outer detachable heel part 32 is in place below and in contact with the outer surface of the inner permanent heel part 13 as shown in Fig. 1, the forward edge or upper forward margin of this detachable heel part 32, together with the forward marginal edge of the supporting plate 34 carried thereby, will overlap'upon the outer surface of the rear end of the outer detachable sole 22 so as to cover not only the projecting lug 24 thereof but also so as further to overlap upon this outer detachable sole 22 at the outer side thereof, and in the construction shown in the drawmgs this overlap on the rear end of the sole 22 is substantially to the extent of the thinned or tapered marginal v:'-.pectively with apertures 36 and 37 beneath.

or below which there are corresponding recesses in the material of the outerheel part 32 for the reception of the respective outwardly projecting studs 17 and 18, as shown in Fig. 1. At a substantially central point thereof the supporting plate 3 l is provided. with a bolt-receiving. apertureBS, and atv this point below or back ofthesupporting.

plate 3l a suitable recess is provided in the material of the outer heel part 32 for.the.

reception of a nut 39, as shown in Figs. 1 and 6.

The outer detachable heel part 32 is adapted to be firmly yet detachably held in place by means of a screw bolt 40 passing outward from. the inside of the heel of the shoe through the central hole 20 provided therefor in the upper metallic stud-carrying plate 16, then through the aperture 21 in the upper permanent heel part 13 and through.

the central opening 38 in the supporting plate 34 and into engagement with the nut 40, which, as above noted, is held in place in the outer detachable heel part 32 by means.

insole 2, as is shownin Fig. 1, this covering plug 41 being readily removable by any slmple means, such for example as by means of the screwdriver which is employed for removing the bolt 40.

It will be noted that the outwardly pro? jecting studs 17 and 18, passing, asabove described, through the supporting plate 34: and into the material of the outer heel part 32, not only prevent rotative movement of the outer heel part 32 upon the attaching bolt 40 as a pivot but also theforward one of these studs 17 is assisted in its hereinbefore mentioned function of holding the detachable outer sole 22 in place by reason of the interlocking engagement ofthis stud 17 with the outer heel part 32, as is clearly shown in Fig. 1. When the attaching bolt.

40 is tightened it not only firmly and securely yet detachably holds the outer heel part 32 in place and in firm contact with the lower surface of the inner permanent heel part 13 but also the upper surface of the forward margin of this outer heel parti32 presses upward upon and firmly holds and locks in place the rear end of the outer detachable sole 22, as most clearly appears in Fig. 1, so that the parts of the shoe are firmly yet detaehably held together.

The'transverse arrangement of the keeper straps 7, 8, 9 and 10 below the. permanent inner sole 2, together with the securing of the independent attaching tongues directly to the outer sole 22 by the attaching rivets 30, provide for the transverse bending of the shoe in walking. without any interference whatsoever from such attaching means for the outer detachable sole 22, as will be readily understood, the operation in this respectbeing. substantially the same as in shoes as heretofore commonly manufactured with outer soles and heelspermanently secured in place, such as .by sewing ornailing, so as not to be readily renewable by, the ordinary wearer himself.

For removing the outer detachable heel part 32, obviously it is only necessary to re move the attaching bolt 41-0, thereby permit: ting the. outer heel part 32' to be simply lifted off; Afterithe outer removable heel part 32 has beenremoved or detached, then the outer. detachable sole part 22 may next be.

readily, removed or detached. This is accomplishedby first disengaging the lug 2a of the outer. detachable sole 22 from the studl'l. By-pressing gently upon the heel andtoe of the shoe and at the same time slightly bending the shoe, the lug 24 will havea tendency to move outward on the stud 17, sufficiently so that the rear end of this. sole .22 can be grasped by the fingers, but if in any case the lug 2%.should show a tendency to stick, then it may be readily loosened by the end of the screwdriver inserted as a lever at the rear end thereof, as will :be .readily understood. After: the lug 24E of the outer detachable sole 22has been freedfrom the sole-retaining stud 17 it is then. only necessaryto. push the sole 22 forward relatively to the other parts of the shoe for thereby entirely disengaging-and removing it, the forward toe hook 31 thereby being. disengaged and the respective attaching-tongues 26, 27, 28and .29 being by this forward movement withdrawn from above the respective loop-forming straps or keepers 7, 8, 9 and 10. After the detachable outer sole 22 and the detachable outer heel part .32-have beenv thus removed, they may be replaced by new and unworn similar parts,,as is obvious The shoe ofimy invention..,is to .be made up and sold with outer sole and heel attached andas is illustrated in Fig.1 of the drawings, and then'when the soleand heel, or either of them, wear out it is proposed that the wearer himself remove the worn outer sole and heel and attach in place thereof anew sole and heel which he can ,buy. at the same store where he bought the shoes, and .a supply of which if desired or made necessary by any. particular circumstance. may be kepton hand by the wearer of the shoes -It is obviousthat various modifications may. be made in the construction shown in the drawings and above particularly described within the principle and scope of my invention.
